. METAE-woRRINe MACHINE.

To aZZ whom t may concern:

Be it known that I, EDwARD'V. WURTs, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Meta-l- Vor-king Machines, of which the following is a specification.`

The invention relates to metal working machines, and more especially -to machines in which structural shapes, or like heavy work are successively traveled and accurately stopped to be punched for rivet holes or like operations, the machine being especially adapted for use in the fabrication of structural shapes.v More particularly, the present invention relates tov means and mechanisms for accurately stopping heavy shapes with accuracy and precision for widely varying successive distances of travel with the greatestvdesired degree of closeness of subdivision of distance units, and in connection therewith the invention also'relates to devices for automaticallycontrolling 'the movements of such ldistance determining devices, such controlling devices including the restoration of the mechanism to an initialv Or normal position after a distance reading has been effectuate-d, that is, after a shape has been stopped in accordance with a distance setting. Other objects of the invention will be set forth hereinafter in part, and in part will be obvious herefrom.

The invention consists in vthe novel parts, arrangements, constructions and improvements herein shown and described.

The accompanying drawings, referred to herein and constituting a part hereof, illustrate one `embodiment of my invention, and together with the description serve to eX- plain the principles thereof.

Of the drawings: f

Figure l is a fragmentary top plan, with parts in section and with parts broken'avvay,

Fig. 2 is a vertical transverse section, on 'anfenlarged scale, onr the line A-B of Fig. l; t

Fig. 3 is a transverse vertical section, likewise on an enlarged scale, on'the line C-D of Fig. l;

Fig. 4 `is a transverse vertical section on the line E-F of Fig. l, being also on an enlarged scale; and

Patented Sept. 25, 191 7.

Application filed July 1o, 1915. serial No. 39,080.

Fig. 5 is a diagrammatic view of certain mechanisms and wiring relating to the shape, stopping and positioning means, and to the means for controlling the positioning means and for restoring' it to initial or normal position.

Fig. '6 is a fragmentary sectional view from the lower central part of Fig. l.

In the machine constructed in accordance with my invention, which is illustrated in the accompanying drawings by way of example, means are provided for traveling the shape x along a horizontal pathway past punchingmechanism or like tool equipped means, the locationof which tooll equipped means is indicated generally by the letter y applied to the housing. In conjunction therewith means are provided for stopping the traveled shape in selected predetermined positions to be punched for rivet holes, said stopping means comprising devices engaging the shapeto hold it firmly and accurately and also comprising selective settable means, having settable devices representing distance denominations and distance values in the denominations, such means operating automatically to control the stopping and positioning of the shape in conformity' to the .settings made. In accordance with certain features of the invention such selective settings of the mechanism to represent desired distances may be effected automatically by suitable means, such as a distance n record sheet. y f

In :the embodied form of mechanism, the shape :n rests upon a horizontally arranged series of driven rolls 2, which rolls are carried in bearings 3 mounted upon frames 4. The rolls 2 are driven in a suitable manner,

and for thisfpurpose there are provided y beveled gears 5 fixed to the respective shafts of the rolls 2, the gears 5 intermeshing with beveled gears 6 -iXed upon a shaft 7. The shaft 7 extends longitudinally along the pathway of the shape and is rotatably mountedin bearings 8, which bearings are mounted upon one of the frame members 4. The shaft 7 is driven in a suitable manner, and in accordance with certain features of the invention, the rolls 2 may be started and stopped and correspondingly accelerated and retarded in harmony with the operations of the vstopping and positioning means. In the embodied form, a gear wheel 9 is shown xed upon the shaft 7, said gear wheel inter- `the solenoid head. In connection with the gear wheel 49 a stop is provided of suitable .'form, and as embodied, there is formed in vthe gear .wheel 49 an arcuate slot 62, the

end of which serves as a stop engaging a selected projected pin 56. c

Extending backwardly along the shaft l50 from the head 56, and integral withorliXed tosaid head,` is a sleeve 63 to` which is fixed a circular plate 64, the plate 64 `facing closely upon the cylindrical `frame member 54. Inthe plate 64 are a series of arcuate slots 65, corresponding in the present embodiment yto the various siXteenths-of-an inch.

In the cylindrical frame piece 54 are mounted one or `niore annular series of solenoids 70, said solenoids, like the series 57 for.v the inches, being selectively energized from the keyboard or series of automatic contacts 7l. Fixed to the core 72 of each of the solenoids 71 is a pin 78, which pins are longitudinally reciprocable in apertures in t-he annular face of the frame piece 54. The pins 78 are projectable into and retractable from the arcuate slots 65 in the plate 64.

It willbe understood that after the latch 24 has engaged with the selected notch 23 in the rail 21, that rotation of the gear 49 as permitted and determined bythe settings of the pins 59 and-78 will cause rotation of the shaft 29 and thereby longitudinaltravel together of the block 25 andl latch 24, and therewith of the rail28, the head 20 and the shape m to effect the inches and fractions-ofy an-inch for completing the set or vpredetermined distance or measurement. The machine may be operated upon the system of over-all measurements from the end of the work, which system is in general use.

The initial position of the gear49 and of' the plate 64 may be determined by permanently projected pins, or such pins may be wired to be projected at the right time and in proper relation to the other pins.

Referring to the Wiring diagram of Fig. 5, a represents a seriesof contacts or switches which correspond to inches and these contacts are made or closed by the setting of the corresponding stop pins of the Series 59,`

(Figs. l, 3, 4, 5 and 6). There is a like series ofcontacts or switches b for the siX- tcenths ofan'inch, likewise made or closedk by the corresponding stop pins of the series 7 3 (Figs. l, 3, 4, 5 and 6)` and likewise opened when their pins are restored.

At cy is a switchvor contact, which may be regarded as a stop contact, and which is closed when the gear 49 and plate 64 and krcoperating devices are at the restoredl or initial position. Two oppositely acting switches e and g are provided in the circuit` for the motor controller, one being in the forward circuit `and the other inthe reverse 7@ circuit, to govern or determine the direction of the motor drive. The switches e and -g are reversely or oppositely opened and closed by a solenoid d. At 7L is a switch controlling both circuits to the motor controller, which switch is controlled by a solenoid j, and le represents the lines to any4 source of power. At m and n are reversely operating interlocking switches making a holding circuit for the solenoid al. A source of current for the solenoid circuits is shown at p. At F andA R are indicated the connections to the motor controller for forward .and reverse running.

' Consldering the machine as at the end of 85 its cycle of operation a new setting is made. Current from p flows lthrough closed contact a and through closed contact Z) to solenoid j thereby closing switch It. Current from the line k flows through the switch 71,

and through switch g to R, in the motor controller, and the motor 52 reverses, driving the mechanism back to the initial position for the new setting.

i At or coincident with the initial position,

contact 0 closes, and current lfrom 79' flows through contact cy and solenoid ai, thereby opening switch g and closing switch e, and thereby closing the circuit F on the motor controller, and the motor starts forward.

As' the machine goes ahead, contact c opens but interlock m having closed, current from p goes throughinterlock-a and interlock fm to solenoid d, holding switch e closed for forward running until the reading is conpleted, that is, the work stopped in position and the punching effected, when the stop pins are released.

Contacts a and open and allow switches l1. `and e to open, thereby stopping the motor and leaving the mechanism in initial position, to repeat the cycle on the next setting. When the rail 2l advances to a point` where trolley shoe 35 meets the live segment 33, the latch 24 sets, and current is 115 also delivered through the contact 34 to the return circuit, closing the switch s in the line of the motor controller for forward running.

The invent-ion in its broader aspects'islzo notlimited to the precise `form of mechanism shown and described, nor to any precise form, 'but changes may be made therein within the scope of the accompanying claims,

without departing from the principles of the invention and without sacricing its chief advantages.
